To all wlwm it may concern:

Be it known that I, WILLIAM S. A'rwoon of the city-of Montreal, in the Province 0 Quebec and Dominion of Canada, have invented certain new'and useful Improvements in End Stifleners for Railwa' Care, as fully described and claimed'in the ollowing state .ment.-

This invention relates 'to end stifleners ada ted to be used in the construction of stee cars. In building steel cars of yarious it is found 'very desirable to support the end of the car body a ainst stresses due ,with the webs, and the ends of the rib are.

,t'o shifting. of the load, bu ging of the sides, and-other stresses due to sudden stoppingor 'shuntin of the cars.

- The 0 ject of this invention is to provide an inexpensive and eflicient stifi'ening brace that can preferably be made of pressed steel and that can secured to the end of the cal" in such a mannerasto support same with greatstren h and rigidity.

Thedevfi e consists of a substantially U- shaped steel rib having outwardly extending flanges which are ada ted to be securedtothe car body. The llb is strengthened at intervals by means of braces formed integral bent at ri ht angles to overla the sides of the car. I in (place in a horizontal plane and hold the n of the car rigid with respect to the sides thereof.

In the drawings which illustrate my invention: Figure l is a perspective view of y 1 the end of acar showing the strengthening ribs secured in position thereon. Fig.2 is a perspective view of a strengthening Ilb detached. Fig, 3 is a perspective view of an alternative storm of rib. 'Fig. 4 is a sectional I view on the line 6- of Fig. 2. F i 5 is a sectional viewon the line 8- 9 of. F1 2;

. Referring to the drawings,-',1O des gnates a car body showing the strengthening inem bers'll secured to the endsfthereof ata suit-. able distance apart. The strengtheninq 'members, which are substantially 'u shape consist of a pairof approximate? horizontal webs 12 connectedby meanso the in tegr'al flat member'13, at right anglesto the webs. A pair of flan es 14 extend 'outwardl from the webs, orming the; base of said flanges being secured to the car-body. by means of the rivets 15.. The strengthening braces 16, which are formed integral with the rib, are preferably pyramie strengthening ri s are secured.

dal in form being pressed outwardly from the webs 12 in such a manner that the base rests u on the flange 14 and gradually tapers towar the connecting member 13. The webs 12 reach the highest point at the center of the rib 17, and theends of the rib.

gradually taper ofl' toward "The flanges 14 are bent at right angles to the strengthening rib at each end to form the end flanges 18 which are adapted to be secured to the side sills of the car to hold the end of said car rigidly with respect to the sides thereof. In Fig.- 2 it. will be noted that the webs of the rib are ta ered down to terminate at the'point where t e end flanges 18 are bent at right angles to the plane of the strengthening member, the said end flanges 318 being flat upon the outer surface and of the thickness of the flanges 1-1. In

Fig. 3 an alternative form is shown in which the webs are continued around the end flanges 18 and terminate at the outer ends of said flanges, as indicated by thenumeral 19.

Y The strengthening members bein positioned horizontally and being rivete to the end of the car, and having the end flanges 18 overlapping 'the sides and being tied thereto, the rigidity of the end of the earwill be greatly increased and the car able to withstand shocks and stresses due to shifting of the load, shunting of the car, or bulging of the sides.

Having thus described my invention, what I claim is 1. An end stifi'ener for cars, comprising a U-shaped ribbed member formed of a pair of horizontal webs having a connecting men 1 ber ,at right angles thereto,-side flanges extending outwardly from the webs, strengthening braces formed integral with the webs,

and-end fi'angfe's'bent at right angles to-the' plane of the stifi'ening member being positioned horizontally with respect to the end of the car and the end flanges being tiedto the sides of the car, substantially as described.

2. A device of the character described comprisin a .U-shaped ribbed member formed 0? apair of horizontal webs connected by an integral flat member, side flanges extending outwardly from said webs,

end flanges bent at right angles to the sideflanges, pyramidal strengthening braces formed integral with the webs, said device being'po'sitioned horizontally with respect to the end of'the car and adapted to tie the end of the car body to the sides thereof, substantially as described.

-3. A car body comprising a vertical end member tied to the side members by means of a horizontal strengthening rib comprisin a U-shaped member formed of a pan- 0 horizontal-webs having integral strengthem ing braces, and flanges extendingputwardly from said webs, said flengesvbemg bent at -the ends at right angles to the plane of he 10 strengthening member, substantially. as descrlbed.

In witness whereof I have hereunto set v my hand in the presence of two witnesses.
